Network Intrusion Detection

What is network intrusion detection?

A network intrusion detection refers to any unauthorised or forcible action on an electronic network. These unauthorised acts usually threaten the security of electronic networks and their confidential information. However, in order to effectively handle this, companies need to have a cyber-security team on-site at all times.

There are different ways that a hacker might be able to breach the system. Some of these would be through malicious software, other would be through a Trojan horse, and some would even be via a password stealer. There are also different tools that can be used for hacking into a network. There are actually several types of systems that would provide hackers with the necessary tools and information to accomplish this objective.

The networks that these tools are typically installed on are the ones that are meant to secure a company’s network. The systems that are installed on these networks would provide the hacker with the ability to access sensitive information on these networks. These tools will most likely then send an email or other type of notification to the company that was used. This is one of the main reasons why companies should ensure that they have on-site cyber security professionals on-site whenever they are dealing with a network security issue.

However, this is only the beginning of the way that a malicious tool would be able to penetrate their network. Another tool that is most likely to be used would be a virus. A virus can cause a great deal of damage to a network. The amount of damage that a virus can do varies based on the target. These include computer viruses, worms, Trojans, malware, and malware that have embedded itself on a company’s system.

Using a network protection service

There is no way to guarantee the effectiveness of the security that is provided by a company’s networks. However, this could be further mitigated with the use of a network-protection service. This would allow a company to detect malicious activity within the networks as it occurs, as well as prevent further access by stopping the intruders from entering into the system. It would also act as a safeguard against any additional damage being done to the company’s network, should an actual attack occur.

Therefore, it is always important to make sure that a company hires an expert in network protection services. It is also essential that they look for any signs of system intrusion, including the way in which intruders have entered the system and what software or other means of communication they used. The experts would then be able to pinpoint the source of the problem so that they can take preventive measures to protect the company’s network from further damage.

What Is A Next Generation Firewall?

What is Next Generation Firewall?

So what is a next generation firewall? How does it work and who needs one? These are some of the questions asked by IT Security specialists, but there is little information available that answers them.

What is a firewall?

Firewalls are essentially a layer of software that acts as a barrier to prevent someone from accessing their data or system. Firewalls are used for many different reasons; protecting your computer from hackers, stopping people in your home from installing harmful software, preventing people from gaining access to your bank accounts or credit card details, and preventing your children accessing your computer. Firewalls can be installed in various ways, with one of the most common being the use of a firewall software. There is also an installation of software known as “Internet Connection Firewall” which is an effective and cheaper alternative.

What do firewalls do?

Firewalls are designed to perform a number of tasks. For example, they are designed to stop people from gaining access to your computer, blocking hackers or other people from gaining access to your system. They can also monitor what internet websites you are visiting and block them. Firewalls are also used to limit the amount of bandwidth you have on your system and prevent it from using the majority of your hard drive space.

Many people don’t realise how much bandwidth is used on their computers when surfing the internet. As a result, many people are using a lot more internet than they think they need. This leads to a lot of files being saved and deleted quickly, leading to slower speeds and decreased file sharing capabilities. This in turn results in the need for firewalls to keep the speed of your computer up while limiting the amount of files stored in the computer. One of the most common uses for firewalls is to protect your internet browsing activities.

Firewalls are often very expensive as well. If you aren’t careful about what you download and install, you may find yourself spending a large amount of money on anti-virus programs to combat the malicious software that gets placed on your computer. There are some firewalls available that are free, but these may not have a good enough security program or firewall. to be able to properly protect your computer and you might run into problems that could even make your system corrupt.

Firewalls have come a long way from the days of simple one-way firewalls. They are now multifunctional systems that not only help protect your computer from unauthorised access, but can also offer additional features such as protection against viruses and spyware. to keep your computer safe.

How do next generation firewalls work?

Next generation firewalls or NGFW as they are sometimes called, use both static and dynamic packet filtering and VPN support to ensure that all connections between the network, internet, and firewall are valid and secure.

Next generation firewalls are configured to be able to to filter packets based on applications. These firewalls have extensive control and visibility of applications that it is able to identify using analysis and signature matching. Next generation firewalls can use whitelists or a signature-based IP addresses to distinguish between safe applications and unauthorised applications which may be attempting to access the systems and network and are then identified using SSL decryption.

What are the benefits of using a next generation firewall?

Next generation firewalls are able to potentially block malware from accessing a network. This is a process that traditional firewalls cannot achieve. Next generation firewalls are also  equipped to address Advanced Persistent Threats (APTs).

In summary, next generation firewalls can provide a relatively low-cost option for companies looking to improve their basic security as they can provide a number of solutions in one framework and cover of the the work of antiviruses, firewalls, and other security applications.

The Benefits Of Cyber Resilience

The Benefits of Cyber Resilience

A lot of people have started to see the importance of cyber resilience. Cyber vulnerabilities and cyber attacks are happening more frequently and people are starting to realise how critical it is to keep their computers and networks protected. This article will cover the many advantages of a secure and resilient internet and how you can use these to your advantage.

What is cyber resilience?

Put simply: Cyber resilience is the ability to prepare for, respond to, and recover from cyber attacks.

With the constant threat posed by hackers and cyber criminals the need for an internet that is as secure as possible has become crucial. To be able to achieve this level of protection, the internet should be able to handle any type of hacking attempts that might occur. The main goal of a robust internet is to maintain the integrity and reliability of all information on your computer. If one piece of data is lost, stolen or corrupted the entire internet would suffer and this is a big no-no.

How to improve your cyber resilience

The four elements of cyber resilience

1. Manage and protect – identify, assess and manage the risks associated with network and information systems, including those across the supply chain.
2. Identify and detect – continual monitoring of network and information systems to detect anomalies and potential cyber security incidents
3. Respond and recover – Implementing an incident response management programme and measures to ensure business continuity will ensure that you can continue to operate even if you have been hit by a cyber attack, and more importantly get the business functioning once again as quickly as possible
4. Govern and assure – ensure that your programme is overseen from the top of the organisation and built into business as usual.

Cyber security comes in different forms. There is a lot of talk about using software to help protect your computers from the harmful effects of malware. Other ways include the use of anti-virus programs and firewall programs. The problem with these types of protection programs is that they are not perfect. They are designed to be able to prevent attacks from being successful, but they are often unsuccessful in doing so.

There is also the option of using dedicated servers to give your computers and networks the internet access they need. This type of internet security is great because it allows your information to remain safe and secure, even when there is a hack. However, like other forms of protection the server hosting your website should be completely reliable, and it should be able to handle a large amount of traffic without a hitch.

Many online businesses use a system called the cloud to help manage their online resources. The cloud basically works by providing the company with an easy to use interface and management software. This type of online infrastructure can easily handle any type of cyber attack or hacking attempt and is ideal for those who are looking for an affordable solution for keeping their network safe.

Cyber resilience is an important part of keeping your information safe and reliable. By using a reliable type of internet, using software and employing a system that protects against all types of attacks you can rest assured that your system is going to be up and running when you need it to be.

Sigma Cyber Security specialise in providing our clients with cyber resilient infrastructure and more importantly the architecture to make sure that if any vulnerabilities are identified that these are dealt with efficiently to reduce the impact which they may have on the business and its assets.

How to Stop Ransomware

If you’re one of the millions of people worldwide who’s been affected by a malware infection, you’ve probably noticed a sudden spike in how much your computer is being asked to pay to remove the virus. There’s a good reason for this: in many cases, the removal program you use isn’t able to actually remove the infection once it’s on your system. This article will explain why you should never purchase anti-virus software that can only be removed after a hard disk crash or a program has crashed.

What Is Ransomware?

Ransomeware is a type of malicious software designed to block access to a computer system or specific files on a computer system until a sum of money is paid.

How to manage Ransomware?

The main reason why you need to be able to remove your ransomware infection on your own is because the infected files are continually being re-infected onto your system. This means that it’s virtually impossible for the removal program to keep running on your PC. In addition, if you try and delete any files from your computer using the wrong method – such as deleting the files by pressing the F5 button, then trying to re-install them afterwards – then the chances are they’ll be re-infected again.

How Does Ransomware Work?

There are a number of vectors ransomware can take to access a computer. One of the most common delivery systems is phishing spam — attachments that come to the victim in an email, masquerading as a file they should trust. Once they’re downloaded and opened, they can take over the victim’s computer, especially if they have built-in social engineering tools that trick users into allowing administrative access. Some other, more aggressive forms of ransomware, like NotPetva, exploit security holes to infect computers without needing to trick users. Originally featured here.

How to prevent ransomware

One way to prevent this is by using an anti-virus program that’s capable of removing both the ransomware programs, as well as the other programs that have been installed on your computer. There are a number of advanced antivirus tools which are sophisticated spyware applications, and the software uses these skills to detect and remove all the infections that have been placed onto your system. It works by scanning through every file that is currently on your PC and then deleting each of the infected parts that it finds. Not only does this remove the actual infection, but it also destroys any settings & data that were inside it.

Ransomware is able to remove this infection without harming any of the important files & settings that your computer requires to run. Unlike most of the similar products on the market, it can work to remove all the infections that have been placed onto your system without any loss of your personal information. You can also expect to see a huge reduction in the amount of time that it takes for it to work. Ransomware removal software normally takes around 10 minutes for the best results – and the vast majority of users will find that it can remove this infection in half that time.

The problem with most anti-virus tools is that they either do not do a good enough job of removing malware from your PC – meaning that even if you have a working anti-virus program, you could still end up infecting your system with a ransomware infection. Sigma Cyber Security select advanced software solutions which use special algorithms to scan through your computer and identify any infections.

The very best ransomware solutions also offer backup solutions, so that if your computer or system does get infected you won’t lose any data.

Ransomware security software is not normally installed on your PC or laptop, it work by scanning through the system periodically and identifying any potential vulnerabilities in terms of files and their authority and other settings. For most setups you will run the ransomware security software in the background and it will automatically remove the infected files from your machine in a few minutes time.

Once you’ve downloaded the software and installed it on your PC, then all you need to do is to allow it to run. It will perform a scan every time you boot up your computer and will remove all the files from your system, which are known to have been infected with this malware.

Sigma Cyber Security provide an offer a number of different ransomware solutions to our clients depending on their cirumstances. Get in touch with our team today to discuss your ransomware requirements.

What Is An SQL Injection and How Can It Hurt Your Business?

What Is An SQL Injection and How Can It Hurt Your Business?

Here we will discuss some of the commonIf SQL Injection vulnerabilities that could easily hurt you or your company. By the time you’re done reading this article, you will have some pretty good knowledge about the potential problems that can be caused by SQL Injection.

What is SQL?

SQL stands for Structured Query Language. A query language is a kind of programming language that’s designed to facilitate retrieving specific information from databases, and that’s exactly what SQL does. To put it simply, SQL is the language of databases. (Further details: https://www.dataquest.io/blog/sql-basics/)

How Does An SQL Injection Work?

A great description is provided by our pals over at IT pro:

A SQL injection attack is when a third party is able to use SQL commands to interfere with back-end databases in ways that they shouldn’t be allowed to. This is generally the result of websites directly incorporating user-inputted text into a SQL query and then running that query against a database. How this works in a non-malicious context is that the user-inputted text is used to search the database – for example, logging in to a specific account by matching it based on the username and password entered by the user.

The most common way to cause SQL Injection vulnerabilities is to use a parameter that is not properly sanitised. This includes anything that is passed as a parameter to a SQL query. A common example of this is to pass an email address in your SQL query for a particular type of marketing. This information would normally be secure because email addresses are typically unguessed and encrypted.

Another common technique is to use the use of an improper type conversion. As mentioned above, email addresses are normally encrypted and unguessed. If a user enters an incorrect email address into a web form or database, they could potentially steal or damage that person’s data. To avoid this problem, always be sure to use an email address that has been securely encrypted. Also, always be careful to use the email that is unguessed.

It is also possible to to cause an SQL Injection by using a table that is not set up correctly. If you have a table in a table, but you don’t use any security in the column, this can cause some serious damage. If you are using a table with security, then the attacker will have to guess at the column name to get the data.

Another problem that could cause SQL Injection is by using the improper types of SQL functions. Many people use a table, such as a VARCHAR, as a temporary table when they are working on a long table. This causes the VARCHAR to become vulnerable to SQL injection attacks.

If a mistake has been made in the SQL code this can create SQL vulnerabilities. It is always recommended that you engage the services of a professional for coding, it is also good practice to keep a backup of your table so that if something does happen, you can roll back.

AN SQL Injection is a very dangerous problem that can easily cause major damage to your company, or a company that you are associated with. You need to be aware of the issues that can occur because you never know which one of them will occur.

How To Protect Your Business From An SQL Injection

It is important that you learn as much about SQL injections as you can. By taking some classes in SQL injection, you can keep your business secure.

You should make sure that your web page is encrypted and you also make sure that you are using the correct types of columns for your database. If you find that you cannot afford to hire a professional, you can still protect your information by using some basic techniques.

Some common ways to avoid SQL Injection include not using the wrong types of security for the columns you tables. You should make sure that you use secure input and output data. The last thing that you want to do is to make the wrong choice when creating a table because it can cause a big issue later down the road.

Always be sure that your company is using the right type of security. and be sure to make sure that you are using the correct type of security for your table. If you make the wrong choice, it can cause major damage.

Sigma Cyber Security engage the services of a number of SQL specialists to assist our clients with identifying potential SQL vulnerabilities and also identifying potential fixes, please get in touch with our team to discuss your requirements today.

Cyber Insurance

What Is Cyber Insurance?

Cyber Insurance is a specialist insurance which is designed to help  your business to recover financially after a data security breach, with potentially serious losses that can range from business interruption, product damage, loss of revenue, legal costs, public relations costs, and other costs associated with legal mandated notifications and required forensic analysis. Your company might also be forced to reimburse third-party vendors and employees whose personal information or data has been stolen. In addition, your business might be required to make a public apology or even retract false information published online, resulting in lost customers, and the loss of customers’ goodwill. This scenario is why it is important that you consider protecting your business against cyber theft, which can occur through several channels.

While there is no way to stop a cyber attack from occurring, a company should be proactive in its response to ensure that it will not interfere with the normal operations of your business. Your company should determine if the risk of a breach is high enough to warrant the investment in data security, which could save you tens of thousands of dollars. Cyber insurance should be considered for any business that stores sensitive data, such as financial records or customer credit card numbers, because the cost of such an insurance policy would likely be less than the value of the data that is at risk.

How Does Cyber Insurance Work?

Cyber Insurance works like most other insurance policies, you pay an insurance premium, which an actuary calculates based upon the type of information involved and risks involved with your business. The insurance company may require some level of ethical hacking including penetration testing to be implemented as part of the policy to identify potential weaknesses in the business and its infrastructure. The insurer may also some level of training to ensure that staff members are aware of cyber attacks and actions which they can take regarding ensuring they reduce the risks to the organisation. If the business does get hacked, then the insurer will pay out either a monthly payment or a lump sum depending on the impact of the hack and the costs involved in repairing it, along with potential reputation damages which may be incurred.

With the purchase of such a policy, you would be covered not only for the damages caused by a breach but also for the costs of restoring your business to a comprehensive plan to protect against future breaches, should one occur. Such comprehensive plans would consist of software programs that will block hackers and other forms of malicious software from accessing your system, computer networks that are highly secured to prevent unauthorised access, back up systems that will protect sensitive documents, networks that are password protected to prevent users from gaining unauthorised access, and servers that are protected from firewalls and malware to prevent the damage from spreading to your business’ servers.

Such comprehensive programs will also prevent your data from being compromised, which can occur due to a variety of reasons, ranging from human error to software glitches. Some common causes of data corruption are malicious virus infections, keystroke capture programs (KAP) and data file corruptions. In order to avoid such risks, you should update your software, network security, and servers regularly to ensure that they are always secure and safe.

Security breaches are not something that can easily be prevented, but with proper protection, you can avoid them completely. A comprehensive program can help you avoid potential damage that could compromise your business ‘reputation, which could result in lost business and the loss of customer loyalty, loss of clientele, and the loss of future sales, as well as the loss of your business’ reputation as a whole.

With a comprehensive plan, you will be able to recover financially, quickly and fairly after a breach, making it possible for you to keep your business afloat without incurring significant financial loss. If you do not have a plan, you can still recover in a short period of time, although this could require the assistance of your insurance broker. The insurance company would work with you to determine the best course of action to cover your needs and make sure that your business is back on track.

Cyber attacks are not something that you can afford to ignore, so it is important that you protect your data and keep your data secure. in order to avoid costly mistakes, such as downtime. By getting a comprehensive data security system that protects your company’s database and files, you can ensure that no one has access to information that could potentially affect your business, even if they are not authorised to access it.

Sigma Cyber Security work closely with a number of insurers implementing cybersecurity training, implementing cybersecurity strategies and much more. Get in touch with our team today to discuss your cybersecurity requirements.

The Different Levels of Network Security

Network security is the process of protecting and preventing unauthorised access to commercial networks. As a theory, it complements end-point security, which mainly focuses on physical devices; this means that network security focuses more on how these physical devices are interconnected, and more importantly, on how they interact. While end-point security mostly deals with the security of the communication links between an organisation’s users and its information systems, the network-level security provides a level of protection that doesn’t always have to be coupled with end-point security. This is because while end-point security is usually coupled with network security in order to keep information secure, network security can also work independently.

When considering network security, it is important to think about three different levels: the physical layer (which is the protection layer), the middle layer (which is the security of networks themselves) and the end-user layer (which is the security of an organisation’s computer network). In order for a given system to be considered secure, one needs to consider all the layers in order to provide maximum protection against attack. The three levels that network security encompasses are physical layer, security of networks, and the end-user layer.

Physical security refers to the security of physical networks (for example, networks that are connected to the outside world); this includes the protection of a system from being attacked by outsiders, or even those inside the organisation (as is also done for data, but with different reasons). As such, physical security is a high-end layer that involves the physical isolation of the network and the security of the internal networks that are connected to it. Security of networks refers to the security of networks that is usually not as high as physical security. This type of security mainly covers the security of a network from external attacks, but it also takes into consideration the security of the internal network from outsiders as well, so that when the security of the internal network is breached, this does not allow outsiders to compromise the security of the external network as well.

The middle layer is another high-end layer, which is more like an interface between the physical security layer and the end-user layer. Here, the two layers work together to create an overall level of security for the entire network. Since the middle layer is more like a firewall than the other layers, its primary responsibility is to ensure that no system on the network can get into the network without authorisation, and to maintain the integrity of the network in the event of a system getting into the network.

Finally, the final layer is an end-user layer. It involves the security of an end-user, whether they are an employee or a customer. This layer provides the security of the data that an end-user accesses when using the network, whether it is confidential information, intellectual property, financial data or even personal information. It is important to note that the end-user layer does not cover just the data security; it also takes into consideration the security of the company’s customers in the case of an issue with a service or product that affects the security of the data.

While there are many different levels of network security, it is important to know that each level has its own responsibilities. These responsibilities are very important for any business to understand, since they play a very crucial role in how a business runs.
